Expression profiles of genes related to carbohydrate metabolism provide new insights into carbohydrate accumulation in seeds and seedlings of Ricinus communis in response to temperature.

摘要: Ricinus communis possesses a specific metabolic signature to adjust growth and developmental processes in response temperature: carbohydrates are accumulated at low temperatures, whereas amino acids elevated temperatures. Our objective was assess tissue-specific changes transcript levels of genes related with carbohydrate biosynthesis catabolism temperature. For that, we measured encoding enzymes involved starch biosynthesis, catabolism, gluconeogenesis R. communis leaves, roots, seeds grown 20 °C 35 °C. Transcript were higher leaves than 35 °C, but up-regulation seems compensate for this and, therefore, the likely explanation 20 °C. Higher soluble may be caused by coordinated increase level associated pathways. In seem enhanced germinated temperatures is biosynthesis. Similarly, RcPEPCK RcFBPase most causal fructose glucose accumulation This study provides important insights understanding plasticity temperature that apply other species as well.
